CVE-2026-89996

A flaw was found in the Linux kernel's dma-buf subsystem. A local attacker can exploit a race condition during the DMAHEAPIOCTLALLOC operation. If the copytouser function fails after a file descriptor fd has been installed, the fd is leaked for the lifetime of the process. This continuous leaking...

CVE-2026-5555-Container-Escape-via-proc-self-fd-Symlink-in-Shared-Volume

CVE-2026-5555 – Container Escape via /proc/self/fd Symlink Overview A shared volume mounted with rshared propagation allows a malicious container to create a symbolic link pointing to a host file through /proc/self/fd. The host process writing to the volume follows the symlink, overwriting critic...

SUSE CVE-2026-97983

In the Linux kernel, the following vulnerability has been resolved: vduse: return compat ioctl results directly The compat handler handles VDUSEIOTLBGETFD and VDUSEVQGETINFO, but then calls the native handler. Their different command sizes make native dispatch return -ENOIOCTLCMD. For GETFD, this...

Efficient TCitH-Based Alternatives to SLH-DSA: Cross-Layer ASIC Design of Mirath

To address the security risks posed by quantum computers, the U.S. National Institute of Standards and Technology NIST has standardized the post-quantum signature schemes ML-DSA, FN-DSA, and SLH-DSA. While ML-DSA and FN-DSA are lattice-based, SLH-DSA relies on hash-based assumptions. To support...
